To all whom it may concern.

Be it known that I, Gnonen W. Manxnns, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Dice-Cups, of which the following is a specification.

This invention relates to an improved dice box for shaking and throwing dice in con nection with various games of amusement, the object of the invention being to provide a dice box by the use of which a fair throw of the dice is insured and fraudulent manipulation or arrangement of the dice is prevented.

The object of the invention is effected by providing the dice box with an inwardly projecting conical bot-tom, and by providing the interior surface of the box with means to compel the dice to turn or tumble over and over while being thrown out of the box. The conical bottom compels the die to rest with its sides in an inclined position instead of horizontal and prevents the thrower securing an advantage by fixing the dice, and the continual tumbling of the dice while being discharged prevents the dice being slid out along the side of the box in a predetermined position or arrangement.

In the accompanying drawings, Figure 1 shows a dice box having a conical bot-tom and having a spiral projection on the interior surface thereof, Fig. 2 shows a box having a slightly modified form of projection, the box being inverted as in throwing the dice to illustrate the tumbling action thereon, and Fig. 3 shows a box having a plurality of ring shaped projections on its interior surface.

in Fig. 1, the dice box a; of cylindrical form, has an inwardly projecting conical bottom I), and a spiral projection c extending around the interior surface at of the box. The conical bottom 7) may extend inwardly for any suitable distance but preferably for about the distance shown in the drawings, so that one side of the die 6 rests on the conical bottom and the upper sides of the die are inclined at approximately equal angles. The spiral projection c is shown of triangular cross section, but it is obvious that it may be of other section, such for example as square or semi-circular, with substantially the same efiect.

In Fig. 2, the projection f is partly of spiral form and partly of ring form, one

or more parts 9 of the projection extending around the inside surface of the box parallel to the upper edge thereof, and then continuing in the form of the spiral as shown. This figure clearly illustrates the tumbling action of the projection on the die as the latter is discharged from the box and shows the impossibility of sliding the die out of the box in any prearranged position.

In Fig. 3 a plurality of projections are provided in the form of parallel rings 72. extending around the inside of the box. These rings may be of any suitable distance apart and may be of any desired cross-section, although shown triangular in the It is to be clearly understood that the invention is not limited to the formation of the interior surface of the box'with a single projection of spiral form or with a plurality of projections of ring form, as numerous other arrangements of the projection or projections could be made. For example a plurality of spiral projections could be provided, extending around the inner surface of the box in the same or opposite directions, or one or more spiral projections could be combined with a plurality of projections of ring form. The essential feature of this part of the invention, is that the interior surface of the box is so formed that a plurality of projections are arranged in the path of the die, when being discharged from the box, so that the die is tumbled or turned over and over. The projecting portions could be formed separately from the box if desired and secured thereto by suitable means.

It will be seen that by the usev of the conical bottom, the die always rests in such a position that it has an initial tendency to roll or turn over and over as soon as the box is tilted to discharge the dice.

The dice box may of course be made from any suitable material, but it is preferred to use a stiff soft rubber composition, molded in one piece, as by this means seams are avoided and the box cannot rip or break, and further the box will stand considerable wear and tear without deterioration.

I claim 1. A dice box having its interior surface so formed as to present a plurality of proj ections in the path of a die being discharged therefrom, and having an inwardly extending conical bottom.
